MORPHOMETRIC ANALYSIS OF THE INFRAORBITAL FORAMEN AND ACESSORIES FORAMINAS IN BRAZILIAN SKULLS
The aim of the study was to establish morphometrically the infraorbital foramen (IOF) location in the sagittal and transversal plan of the skull and to analyze the variations, as well as verifying the symmetry with the contralateral IOF. 210 skulls were analyzed and as exclusion criterion, were not...

| Sumario: | The aim of the study was to establish morphometrically the infraorbital foramen (IOF) location in the sagittal and transversal plan of the skull and to analyze the variations, as well as verifying the symmetry with the contralateral IOF. 210 skulls were analyzed and as exclusion criterion, were not analyzed skulls of children. Digital paquimeter was used and had been carried through two bilateral measures: a)sagittal measure; from infraorbital margin until the superior margin of the IOF; b) transversal measure, of the lateral margin of piriformis opening until the medial margin of the IOF, using the transversal plan. These measures had formed an angle of 90 between itself. The data were analyzed by the Kolmogorov-Smirnov to verify the Gaussian distribution and and Person's test to evaluate the correlation, considering significantly the differences that had presented a p 0,05. The mean±SD in the sagital measures were respectively; right side 6,71±1.70 mm and 6,83±1.83 mm for left side (p0.0001). Transversal measures were: right side 13,28±2.17mm and 13,31±2.19 mm for left side (p0.0001). Were observed supranumerary foramens of the IOF, with presence of the double IOF in 50 cases, being bilateral in 08 specimens, left and right side 21 specimens for each side.The IOF are not absolutely symmetrical and may present pair bilateral and or unilateral opening. The presence of the supranumerary foraminas, as well as, the morphometrics measures in this study may intervene with the anesthesia, thus, suggest that they must be considered in the anaesthesical evaluation and be remembered during the procedures used for the localization of the forame |
